Particulates - Wikipedia

The composition and toxicity of aerosols, including particles, depends on their source and atmospheric chemistry and varies widely. Wind-blown mineral dust tends to be made of mineral oxides and other material blown from the Earth's crust; this particulate is light-absorbing. Sea salt is considered the second-largest contributor in the global aerosol budget, and consists mainly of sodium

Air Conditioning System - an overview | ScienceDirect Topics

MERV values vary from 1 to 16, and the higher the MERV value is, the more efficient the filter will be in trapping airborne particles. Another consideration is airflow through the HVAC system. Leaving a dirty air filter in place or using a filter that is too restrictive may result in low airflow and possibly cause the system to malfunction.
